Question

Look at the following number sequence.

6, 9, 12, 15, . . .

Based on the pattern, what are the next two terms?​

Answer 1

the next two terms would be 18 and 21

Answer 2

18, 21

Explanation:

By finding the difference between each term, you can find the pattern. 9-6=3, 12-9=3, 15-12=3, so we know that each term is 3 more than the last.

Therefore, by following the pattern of +3, the next term is 15+3=18 and the one after that is 18+3 = 21
